he device has many functions; therefore various configuration commands and query commands are provided to facilitate device management and maintenance. Huawei access controller registers commands to different command views based on the functions of the commands, so users can easily use them. To use a function, enter the corresponding command view first and then run corresponding commands.

The device provides various command views. For the methods of entering the command views except the following views, see the Huawei Wireless Access Controllers Command Reference. VXLAN Capabilities of CE Series Switches-2787409-1

Thanks for you sharing , about the version match table , can you share one link to us ?
Versions prior to V1R5C10 must collaborate with the SDN controller. V1R3C10/R5C00 can collaborate with the SNC or AC1.0 controller. V1R6 can collaborate with the AC2.0 controller. V1R5C10 can work independently without a controller.

Multiple gateways are often deployed on a VXLAN network to improve reliability. When one gateway fails, traffic can be rapidly switched to another gateway. This prevents service interruptions.

VRRP can be used to improve the reliability. In VRRP networking, only the active gateway can forward traffic and provide the gateway service. The standby gateway provides the gateway service only after the active gateway fails. This switchover mechanism reduces gateway usage and slows down convergence. It is required that reliability be guaranteed and multiple gateways be used to forward traffic to make full use of gateway resources.

I have encountered this question about you. I have checked a lot of information, but I still have not answered this question clearly. Thank you for sharing this knowledge and solving my doubts. I hope that you can continue to update such knowledge points. Thank you. !

High reliability: Member switches in a stack work in redundancy mode. Inter-device Eth-Trunk links can also be set up between the member switches for link redundancy.

High scalability: By combining physical switches into a stack, you can easily increase the number of ports, bandwidth, and processing capability without changing the network topology.

an enterprise has constructed a mature campus network but does not have a dedicated data center network. All the servers of the enterprise are scattered in different departments, and they are interconnected through the campus network. The VXLAN technology can construct a virtual network over the campus network, realizing resource integration and flexible service deployment. To facilitate management and maintenance, VMs with the same service requirements are planned in the same network segment, while VMs with different service requirements are planned in different network segments. For example, VMs in the R&D department need to communicate in the same network segment; VMs in the R&D department and marketing department need to communicate across different network segments.

Comparison is very good

Item	CE12800	TOR	Cisco	H3C	Remarks
Versions prior to V1R5C10 must collaborate with the SDN controller. V1R3C10/R5C00 can collaborate with the SNC or AC1.0 controller. V1R6 can collaborate with the AC2.0 controller. V1R5C10 can work independently without a controller.	YES	YES	N	N	In versions prior to V1R5C10, the control plane is on the controller, and the VXLAN commands can only be delivered by the controller but not configured on switches.
Traffic loops back on the Layer 3 gateway. By default, the CE12800 uses an internal loopback interface. A command is provided to change the interface to non-loopback mode. (Supported by EC and later line cards only.) TOR switches use ports to loop back traffic (connection not required).	YES	YES	Y	Y	For modular switches: H3C uses the same chip as that of Huawei, with a later version; therefore, this problem does not occur. Cisco N7000 does not loop back traffic, while N9000 uses internal loopback. For fixed switches: H3C is the same as Huawei. Cisco N9300 uses internal loopback.
CE switches do not support VSs when controlled by the SNC controller.	YES	NA	N9000 does not support VS.	N
The configurations to be delivered from the SDN controller to devices through OpenFlow must not conflict with existing configurations of the devices.	YES	YES	N	Y	In some H3C solutions, the control plane is on the controller. The solutions have similar problem.
MPLS and VXLAN cannot be configured simultaneously on CE switches.	YES	YES	Y	Y	Chip hardware restriction (N9000 uses the same chips as those used by Huawei fixed switches. H3C all series switches use similar chips as those of Huawei switches.)
GRE and VXLAN cannot be configured simultaneously on CE12800 switches. CE12800 supports VXLAN by default. To configure GRE on a CE12800, modify the configuration and restart all line cards.	YES	NA	N	Y	Chip hardware restriction (N9000 uses the same chips as those used by Huawei fixed switches. H3C all series switches use similar chips as those of Huawei switches.)
TRILL/FCOE and VXLAN cannot be configured simultaneously on CE switches.	YES	YES	Y	Y	Chip hardware restriction (N9000 uses the same chips as those used by Huawei fixed switches. H3C all series switches use similar chips as those of Huawei switches.)

VTEP automatic discovery (dynamically establishing VXLAN tunnels)	Supported	Supported	Not supported	For non-SDN applications of compe***s, static configuration is not required and deployment is easy. In SDN solutions, configuration is made on the controller; therefore, compe***s have no distinct advantages over Huawei.
	Implemented through EVPN or multicast replication	Implemented through private ENDP	The controller dynamically delivers static configurations to devices after calculation.
VNI neighbor automatic discovery (dynamically associating VNIs and tunnels)	Implemented through EVPN or multicast replication	Implemented through IS-IS extension	Same as the above.	Same as the above.
MAC address learning and synchronization	Learn by the hardware IS-IS extension	Learn by the hardware EVPN extension	Learn by the hardware	The number of MAC addresses in protocol-based MAC address advertisement is limited and is not stable. In protocol-based MAC address advertisement, the switches discard unknown unicast traffic, optimizing traffic forwarding.
BUM traffic replication on a centralized point(VMware service node)	Supported	Not supported	Not supported	Implemented through software forwarding by the servers, with low efficiency. BUM traffic replication does not have a high value, and you can take service innovation into consideration.
